NAME
htmldoc - convert html source files into html, postscript, or pdf.
SYNOPSIS
htmldoc [options] filename1.{html,md} [ ... filenameN.{html,md} ]
htmldoc [options] -
htmldoc [filename.book]
DESCRIPTION
Htmldoc(1) converts HTML and Markdown source files into indexed HTML, PostScript, or
Portable Document Format (PDF) files that can be viewed online or printed. With no
options a HTML document is produced on stdout.
The second form of htmldoc reads HTML source from stdin, which allows you to use htmldoc
as a filter.
The third form of htmldoc launches a graphical interface that allows you to change options
and generate documents interactively.
COMMON MISTAKES
There are two types of HTML files - structured documents using headings (H1, H2, etc.)
which htmldoc calls "books", and unstructured documents that do not use headings which
htmldoc calls "web pages".
A very common mistake is to try converting a web page using:
htmldoc -f filename.pdf filename.html
which will likely produce a PDF file with no pages. To convert web page files you must
use the --webpage or --continuous options at the command-line or choose Web Page or
Continuous in the input tab of the GUI.

The following command-line options are supported by htmldoc:
--batch filename.book

ENVIRONMENT
HTMLDOC looks for several environment variables which can override the default
directories, display additional debugging information, and disable CGI mode:
HTMLDOC_DATA
This environment variable specifies the location of htmldoc's data and fonts
directories, normally /usr/share/htmldoc or C:/Program Files/HTMLDOC.
HTMLDOC_DEBUG
This environment variable enables debugging information that is sent to stderr. The
value is a list of any of the following keywords separated by spaces: "all", "links",
"memory", "remotebytes", "table", "tempfiles", and/or "timing".
HTMLDOC_HELP
This environment variable specifies the location of htmldoc's documentation
directory, normally /usr/share/doc/htmldoc or C:/Program Files/HTMLDOC/doc.
HTMLDOC_NOCGI
This environment variable, when set (the value doesn't matter), disables CGI mode. It
is most useful for using htmldoc on a web server from a scripting language or
invocation from a program.
EXAMPLES
Create a PDF file from a web site:
htmldoc --webpage -f example.pdf http://www.example.com/
Create a PostScript book from a directory of HTML files
